概览

AI 生成的概览

核查 AI 回答中引用的标识符是否真实存在：向签发这些标识符的注册机构查询，并生成带签名的报告。

可以做什么
  • 向签发机构核查被引用的标识符（DOI、PubMed、arXiv、ORCID、ROR、ISBN、LEI、ISIN、CUSIP、SEC CIK、EIN、NPI、英国公司编号、域名等）
  • 每个标识符返回四种状态之一：确认为真、确认为假、无法判定、无法访问，并附未核查清单及原因
  • 生成带签名的报告，含报告编号、PDF、注册机构查询记录及每次答复的 SHA-256
  • 提供可分享的报告链接，任何人打开后都能实时重新核查
适用场景
适合在依赖、发布或转发带引用的 AI 回答之前，确认所引标识符确实存在并已登记。它只验证登记情况，不判断文献是否支持某个论点。
运行要求
远程 MCP 端点，使用 streamable HTTP 与 OAuth 登录；首次连接会自动创建免费 Metis 账户。无需本地运行时、软件包或环境变量。超出每月免费核查额度后需付费方案。
安装前请注意
OAuth 登录会创建与该服务绑定的账户；免费额度为每月 5 次核查，Pro 与 Team 方案需付费。报告可通过链接分享，任何拿到链接的人都能查看。服务只保存标识符、位置和哈希而不保存原文，但提交的标识符会发送给第三方注册机构。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Metis Check，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

README

Metis Check

The check every cited AI answer needs before you rely on it. A citation that looks complete and points to nothing costs a correction, a retraction or a sanction. Metis Check asks the registries that issue each identifier whether it exists and what it says. DOI, PubMed, arXiv, ORCID, ROR, ISBN, LEI, ISIN, CUSIP, SEC CIK, EIN, NPI, UK company numbers, domains and more. Each identifier comes back in exactly one of four states: settled true, settled false, not decidable (a person decides) or unreachable (a delay, not evidence). Every check ends in a signed report with its own id, a PDF and a recheck button anyone can press.

By Metis Foundry. One account covers ChatGPT, Codex, Claude, Claude Code, Cursor and VS Code. Every account starts with 5 checks a month; plans.

[A Metis Check report]

A real report: three identifiers settled true, one settled false. Open it and press Recheck.

Try it in one click

The prompt asks Metis Check to check four references, one of them invented. The invented one comes back settled false, with the registry that said so.

What you get

  • Four states, nothing hidden: settled true, settled false, not decidable, unreachable, and a not-checked list with the reason for each.
  • A report that rechecks without Metis: every line carries the registry query and the SHA-256 of the registry's answer; signed JSON and a PDF.
  • Shareable: anyone with the link can open the report and press Recheck; the registries are asked again, live.
  • Private: passages are never stored, only the identifiers, their positions and a hash. Metis never asks for conversation history.
  • Honest scope: Metis Check establishes that an identifier is registered and what the registry says. It does not decide whether a paper supports a claim.

Plans

Free: 5 checks a month. Pro: $29 a month (or $276 a year), 2,000 checks, case law included. Team: $249 a month (or $2,388 a year), 15,000 checks, 5 seats. Checks that cannot be settled cost nothing. Details: https://check-api.metisfoundry.com/check/plans
